The 2006 Yamaha YZF-R1 LE livery, which was a yellow, black, and white homage to Kenny Roberts Sr., is perhaps the greatest livery ever to adorn an R1, straight from the Yamaha factory. Whether you are a loyal subject of King Kenny, or you just enjoy the fetching, yet simple, racing design, the Roberts livery is a treasure to see in any form — but especially so at speed. Giving us a glimpse as to what the 2015 Yamaha YZF-R1 would look like with such a limited edition paint scheme, Oberdan Bezzi has once again whet our appetite ahead of a weekend full of riding. And for you Giacomo Agostini fans, there is something special waiting for you after the jump as well. Enjoy!

After first showing us the Honda SFA and Honda CRF250 Rally concepts, Big Red made good on its promise for another motorcycle concept premiere at the Osaka Motorcycle Show, debuting the Honda Bulldog concept. With the face of a Ruckus, and built to “leisurely” take-on the great outdoors in an unassuming manor, the Honda Bulldog is a stout off-roader that adds a new slant to the term adventure-bike. With wide 15″ knobby tires, a 28″ seat height, and 400cc parallel-twin engine mated to a six-speed gearbox, the Bulldog certainly isn’t what you expect to see bombing down the trails, yet it sorta makes sense.

If you believe the reports coming out of India and Southeast Asia, Yamaha is working on a naked version of its YZF-R25 sport bike. Presumably to be call the Yamaha MT-25, the naked bike would continue Yamaha’s trend of making naked version of its fully faired sport bikes, similar to the recently released Yamaha MT-125 that is available for the European market. With images of the machine testing on public roads abounding, the MT-25 seems likely to see production, so the real intrigue will be in what markets Yamaha makes the machine available. With Honda already offering faired (Honda CBR300R) and unfaired versions (Honda CB300F) of its small-displacement motorcycle in the US, Yamaha could easily go head-to-head with Big Red with the YZF-R3 and an FZ-03 variant, based off the R3 design.

Need further proof that the future of motorcycling will include electrics? Take this recently published patent application from Kawasaki, that the Japanese OEM filed for back in 2011. The claims are fairly rudimentary, though they do include a transmission, with Kawasaki’s lawyers mostly outlining the basics of a motorcycle powered by an electric motor, of course the news is less about the contents of the patent application, and more about the fact that it was applied for, in the first place. When will we see an electric motorcycle concept from Kawasaki is anyone’s guess, though there are two big motorcycle shows coming up in Japan in a couple weeks’ time. In reality, we doubt we’ll see something so soon from Kawasaki, but if the Kawasaki H2 has shown us anything, it is that anything is possible from Kawasaki right now.

Why would KTM be riding around on a camouflaged Aprilia Tuono V4? That is the question of the day, after a spy photographer caught the Austrian company testing in Spain with such a machine. The answer of course points to KTM working on a V4 street bike platform, which shouldn’t be too surprising since KTM CEO Stefan Pierer already tipped the media off to the fact that it is working on a MotoGP entry that would be based around a beastly V4 engine called the RC16. While Pierer confirmed the MotoGP, as well as a track-only consumer version of the GP bike, zie Austrians have been mum about other motorcycles in KTM’s lineup sharing the new V4 powerplant.

Adventure riders, you prayers have been answered. Honda is set to debut a new off-road model at the Osaka Motorcycle Show, the Honda CRF250 Rally. Based off the Honda CRF250L platform, the Rally concept is basically the CRF250L with rally-styled bodywork. The Honda CRF250 Rally concept will get its worldwide debut alongside the Honda True Adventure concept, which we first saw at last year’s EICMA show. This makes for an interesting dichotomy, as the CRF250 Rally is set to look like the CRF450 Rally race bike, while the True Adventure (cough, Africa Twin, cough) borrows heavily from the race bike’s technology package. With Honda showing a 250cc ADV model and a 1,000cc model at the same show, one has to wonder when a consumer-level version of the CRF450 Rally race bike will be ready as well.

After it first debuted in Indonesia last October, the Honda SFA concept motorcycle seems to be getting serious, as Honda will be showing the up-market bike at this weekend’s Osaka Motorcycle Show and next weekend’s Tokyo Motorcycle Show. While Honda only mentions that the SFA concept is a “street-fighter style light-weight motorcycle with a single cylinder engine mounted on a trellis frame,” sources in Indonesia say the fetching small-displacement machine is built around the 150cc CB150R for that market. Whether this means that Honda will make more premium-focused 150cc machines, and bring them to markets outside of Asia remains to be seen, though it is clear that the Japanese firm is taking such an approach under serious consideration.

Italy’s favorite boutique brand will be back at the Isle of Man TT races this year, with a two rider team that includes American Brandon Cretu. Cretu and his teammate Ben Wylie will campaign for Bimota at the big four road races (North West 200, Isle of Man TT, Ulster Grand Prix, and Macau GP) on-board the Bimota BB3 superbike. This is not the first time that Cretu and Wylie have raced together, having shared a pit while at the Wylie Racing team during the 2011 and 2012 Isle of Man TT races. Though the Bimota BB3 was ruled ineligible for FIM events, the international road racing scene has no hang-ups letting the S1000RR-powered superbikes lineup on the starting grid.

We are still waiting for the 2015 MV Agusta F4 RC to break cover officially, but the top-of-the-line superbike from Varese continues to make itself sneakily available to the public. First there were the leaked studio photos, which looked spot-on to the photos MV Agusta USA teased us with at its press launch earlier this year. Now, we have more photos of the F4 RC leaking, though with some changes to the design — namely more prominent “AMG” badging, for MV Agusta’s newest minority partner. The 2015 MV Agusta F4 RC isn’t supposed to arrive at dealerships until June 2015; and when it does, it will be in limited numbers. The F4 RC is MV Agusta’s homologation special for World Superbike and domestic superbike racing classes.

Aprilia Racing boss Romano Albesiano has big shoes to fill. Taking over from Gigi Dall’Igna, Albesiano must continue the legacy of success which his predecessor left for him. He got off to a good start, Sylvain Guintoli lifting the World Superbike title in Albesiano’s first year at the helm. Now comes the hard part, following up on that success and expanding into MotoGP. A small group of journalists spoke to Albesiano at the Aprilia launch in Milan. In a wide-ranging conversation, the Aprilia boss covered many topics, including explaining why the Noale firm came back to MotoGP a year ahead of schedule, touching on what the new bike Aprilia is working on for 2016 and beyond might look like, and the 2016 rules in MotoGP.

Testing alongside the rest of the MotoGP paddock, Suzuki Racing was present again at the Catalunya test, with Randy de Puniet once again turning laps on the Suzuki XRH-1. Now using the Magneti Marelli electronics, Suzuki has the long process of dialing-in the XRH-1’s full potential.

Also a priority at Catalunya was Suzuki’s more powerful iteration of its inline-four engine, which the Japanese OEM hoped would close its gap to the other OEMs. In the hands of Randy de Puniet, the Suzuki XRH-1 was 2.499 seconds off the pace of test-leader Marc Marquez, though that margin comes with an asterisk.

While the rest of the paddock has had since Friday to hone their machines and bodies to the Circuit de Catalunya, Suzuki and RdP did not have that luxury going into Monday’s test. One can also argue De Puniet’s pace to the other GP riders, as with all due respect to the Frechman, Marc Marquez he is not.

With a thousand variables at play (we can even question the validity of test times in general, as teams are testing not qualifying/racing), it is easy to make excuses for RdP and Suzuki as to why the gap remains so far from the other factories, but the end result is that the XRH-1 is a tough character to judge. That makes Suzuki’s return to the GP paddock a bit of a wild card.

With Both of Ducati Corse’s riders praying for a miracle, or a better option, Suzuki could be that salvation. One also has to consider Dani Pedrosa’s rumored $8 million price tag, and the bevy of other contracts that expire at the end of the season. Suzuki’s impending presence is a considerable factor in MotoGP’s game of musical chairs..

Being a difficult factor to judge though has made Suzuki, the Suzuki XRH-1, and Randy de Puniet’s role in all this is very speculative and uncertain. The only thing we can say for sure then is that it will be interesting to watch the limited number of “factory” seats sort themselves out.

Suzuki’s MotoGP test team took advantage of the presence of the MotoGP paddock at Austin to plan a test directly after the Grand Prix of the Americas.

Under the watchful eye of team manager Davide Brivio, the team planned to have test rider Randy De Puniet put in three days of testing at a circuit, as the team had not yet tested the Suzuki XRH-1 at COTA, in a bid to gather more data ahead of their return to the series in 2015.

Unfortunately for Suzuki, very heavy hail and thunderstorms made testing extremely difficult on Monday, leaving the track very dirty and much slower than it had been for Sunday’s race. But testing resumed in earnest on Tuesday, with Randy De Puniet running through testing electronics and another back-to-back test of the two chassis options Suzuki has been working on.

Up until late in the 2013 season, changes in the rider lineup for Yamaha and Honda’s MotoGP squads looked to be limited. Though all four riders will technically be on the open market at the end of 2014, the most likely scenarios for 2015 and beyond looked fairly settled.

Either the lineups of the Repsol Honda and Movistar Yamaha teams would remain identical, or Jorge Lorenzo and Dani Pedrosa might swap seats. The biggest question mark, it appeared, hung over whether Valentino Rossi would continue racing after 2014.

Two major shake ups changed all that. For Valentino Rossi, the replacement of Jeremy Burgess with Silvano Galbusera – and the increased role for electronics engineer Matteo Flamigni – has helped him find at least some of the time he was losing to the three Spaniards who dominated MotoGP last year, making it more likely he will stay on at Yamaha for another couple of seasons. That leaves the situation at Yamaha look more stable than before.

The arrival of Dall’Igna and Tardozzi has had a major impact, and will likely become even more significant as the season progresses. Dall’Igna has greatly improved communications between staff at Ducati’s Bologna headquarters and the race teams at the track, making for a much more efficient organization.

The fourth installment of Suzuki’s four-part video series (part 1, part 2, & part 3 here) on its MotoGP program is out, and this time around the Japanese OEM is talking about the relentless perils of testing, testing, and more testing (no surprises here). One of Suzuki’s biggest hurdles though, as it gets ready for the 2015 season, is switching from its Mitsubishi electronics system, to the spec-ecu being built by Magneti Marelli for Dorna.

The process is more difficult than it sounds. Not only does Suzuki have to do the general development necessary to get the most out of the Suzuki XRH-1 GP prototype (more photos here, too), but then once complete, Suzuki must port those settings to the Magneti Marelli unit. Meanwhile test riders Randy de Puniet and Nobuatsu Aoki are constantly finding things to improve with the race bike, which can require further changes to the ECU software.

No one ever said it was easy to race in the premier class of motorcycle racing, and Suzuki’s efforts prove that point. With the MotoGP proving itself to be an ever-changing landscape for rules and regulations, Suzuki also faces a very slim window to use the bike that they are currently developing. Thus in our minds, their place as the 2015 underdogs has already been solidified well ahead of their debut. Good luck to all of them.

Suzuki is still working with their Mitsubishi electronics unit, not yet having moved to the Magneti Marelli unit which is compulsory from 2014, and coming to MotoGP in 2015 would leave them just two seasons before a new set of regulations is to be introduced, likely to include a rev limit and compulsory spec software. Suzuki face an uphill task.

Despite the challenges, they seem determined to come back to motorcycle racing’s premier class. One sign of their intent is the launch of a new four-part video series on the progress made on the MotoGP project, the first video of which was released yesterday.

For our American readers, it is time to get back in the swing of things from the long Thanksgiving weekend; and for our non-American readers, well…the last few days must have been pretty boring for you (especially for our Canadian readers, who are probably still baffled about why we Americans celebrate Thanksgiving over a month late).

Anyhoo, it is Monday here at Asphalt & Rubber HQ, and while we let the caffeine soak into our veins, we have some high-energy content to help you get going at the workplace job thing. First up is a little video from Suzuki, which has just concluded its 2013 MotoGP testing schedule.

It is mostly just motorcycle porn for racing fans, but to our knowledge the video is the first time that Suzuki has publicly acknowledged its inline-four cylinder engine design for its XRH-1 MotoGP test bike. Suzuki will be back testing in 2014, with Randy de Puniet now solely committed to test-riding the machine for the Japanese OEM.

High on the team’s list is getting its race program to work on only 20 liters of fuel, as well as switching from Suzuki’s current Mitsubishi-designed ECU to the spec-ECU supplied by Dorna and built by Magneti Marelli. Neither task is an easy one as Suzuki gears up for its 2015 return to Grand Prix motorcycle racing.

One of the advantages of actually going to the yearly EICMA show, as opposed to phoning it in like some other outlets do, is that you get see things that don’t find their way into a press release.

Take for example the Suzuki XRH-1 MotoGP race bike prototype that Randy de Puniet has been developing and Davide Brivio has been heading. On display at the Suzuki stand, it was perhaps the most technologically advanced motorcycle at EICMA, yet you would only know that if you went to Milan last week.

Pity poor Jorge Lorenzo. Once again he comes to a test and tops the timesheets, and everyone is talking about someone else. This time, though, he will probably not mind, as he was not really out for glory at the test, just to work on settings before heading to the next test at Aragon on Wednesday. If it isn’t rained off that is.

Lorenzo chose to skip the morning session, preferring to rest after an impressive win on Sunday, but once underway he was quickly up to speed hitting the top three after just a couple of laps, and ending the day on top.

The Factory Yamaha man had been working on setup, but had also tested a new fuel tank. The new tank does not change the weight balance from the current version used by the factory riders, but it does have a slightly different shape to fit under the seat more comfortably and allow Lorenzo to position himself better on the bike.

On the other side of the garage, Valentino Rossi was once again pursuing weight distribution changes to improve his feel with the bike, especially to help him in braking. A more radical change was planned for the afternoon, but a fast crash at Turn 3 left the bike damaged, meaning that plan had to be abandoned.

Rossi returned to the track at the end of the day to test the new rear tire Bridgestone had brought, and was positive about the feel of the tire. The new construction hard rear tire was a clear improvement, Rossi said, and it was good for the hard rear to once again be an option.

So far this year, the only tire that has worked at most tracks has been the softer option, leaving the riders with a de facto rear allocation of just seven rears for a weekend.

Telling perspective riders last week about the decision (so they could make alternate plans for next season), Suzuki was still at the Circuit de Catalunya for MotoGP’s post-race test, joining Yamaha Racing (which elected not to go to the rain-sodden Motorland Aragon circuit), Ducati Corse, and a bevy of satellite and private teams.

Shaking down its inline-four GP race bike, codenamed the Suzuki XRH-1, Nobuatsu Aoki was first-up on the machine. But the day’s real work was done by Randy de Puniet, who put in an impressive 1’42.676 lap time near the end of the day — just over three quarters of a second off the top time set by Jorge Lorenzo.

However, despite the impressive debut for the XRH-1, Suzuki’s official reason for its delay back to GP racing is the pace of development on the project.

Part of that development process surely is for the electronics, as Suzuki is currently using an electronics package from Mitsubishi, though the company expects to switch over to the spec-ECU from Magneti Marelli later this year, in the autumn.

If that all whets your appetite, our favorite Hungarian Photographer/Journalist Niki Kovács (be sure to follow her on Facebook & Twitter) has sent us nine more photos of the Suzuki XRH-1, which are after the jump for your viewing pleasure.

Be sure to note the XRH-1’s staked gearbox (a very Yamaha design), which is mated to the “big bang” four-banger. The twin-spars of the aluminum chassis looks likes like an evolution of the GSX-R platform, which shouldn’t be too surprising — though when Satoru Teradatalked to GPone, he said that Suzuki hasn’t begun work on a new WSBK machine.

Just hours before the development team’s public debut on the track (private debuts here & here), Suzuki has announced that it will return to the MotoGP Championship in 2015, not 2014. That gives the Japanese factory 21 months to develop its inline-four GP bike with test rider Randy de Puniet, and Davide Brivio at the helm as test team manager.

While the Suzuki has not given a reason behind its prolonged return, the fact that the team would have to foot the bill for its Bridgestone tires, as well as its travel/shipping costs, certainly didn’t help justify an early re-entry for Dorna’s prodigal factory, especially if the bike fails to impress on its first direct comparison to the machines of Honda, Yamaha, and Ducati.

Said to still be carrying a grudge for Suzuki (and Kawasaki’s) broken promises, and departure from the series, Dorna’s Carmelo Ezpeleta has given Suzuki no favors in its return to Grand Prix racing. Dorna originally wanted Suzuki to re-enter the series through an existing team, rumored to be Team Aspar, but ultimately had to scrap that plan as no current MotoGP team was willing to take on the onerous task of managing the factory-backed squad.

Still, Suzuki’s return will mean another two bikes on the MotoGP grid, and Suzuki itself will manage and run the MotoGP team. What the will do to the 2013 silly season remains to be seen, but we can’t wait to see some more photos of the still unnamed Suzuki GP bike on the track. A press release from Suzuki Racing is after the jump.
